The effect of thermal times of circulating non-fried roast technique on the formation of (non)volatile compounds in roasted mutton by multi-chromatography techniques and heat transfer analysis.

The circulating non-fried roast (CNR) technology was firstly applied to roast mutton. The formation of (non)volatile compounds in the mutton roasted for 0-15 min was investigated. The samples roasted at varying times were discriminated using GC-O-MS and multivariate data analysis.

Evolution fate of battery chemistry during efficient discharging processing of spent lithium-ion batteries.

Residual electricity in spent lithium-ion batteries (LIBs) may cause safety issues during their dismantling and shredding in pretreatment processes. However, the migration and transformation of pollutants generated from spent LIBs during discharging were rarely reported, which is critical for prevention of pollution risk and facilitation of discharging efficiency. Herein, this work is focused on the evolution fate of battery chemistry during discharging processing.

Surface Stretching Enables Highly Disordered Graphitic Domains for Ultrahigh Rate Sodium Storage.

Hard carbons (HCs) with high sloping capacity are considered as the leading candidate anode for sodium-ion batteries (SIBs); nevertheless, achieving basically complete slope-dominated behavior with high rate capability is still a big challenge. Herein, the synthesis of mesoporous carbon nanospheres with highly disordered graphitic domains and MoC nanodots modification via a surface stretching strategy is reported. The MoO surface coordination layer inhibits the graphitization process at high temperature, thus creating short and wide graphite domains.

Efficient Aerobic Oxidation of Ethyl Lactate to Ethyl Pyruvate over VO/g-CN Catalysts.

Graphitic carbon nitride (g-CN)-supported VO catalysts were prepared by the impregnation pyrolysis method, and their physicochemical properties were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FT-IR), Raman, X-ray photoelectron spectroscopy (XPS), UV-vis, TGA, N adsorption, and H-TPR. These catalysts exhibit extremely high activity and selectivity in the aerobic oxidation of ethyl lactate to ethyl pyruvate. The excellent catalytic performance derives from the high surface-chemisorbed oxygen species.

The Active Sites of a Rod-Shaped Hollandite DeNOx Catalyst.

The identification of catalytically active sites (CASs) in heterogeneous catalysis is of vital importance to design and develop improved catalysts, but remains a great challenge. The CASs have been identified in the low-temperature selective catalytic reduction of nitrogen oxides by ammonia (SCR) over a hollandite manganese oxide (HMO) catalyst with a rod-shaped morphology and one-dimensional tunnels. Electron microscopy and synchrotron X-ray diffraction determine the surface and crystal structures of the one-dimensional HMO rods closed by {100} side facets and {001} top facets.

Excellent photocatalytic degradation activities of ordered mesoporous anatase TiO2-SiO2 nanocomposites to various organic contaminants.

Ordered 2-D hexagonal mesoporous TiO(2)-SiO(2) nanocomposites consisted of anatase TiO(2) nanocrystals and amorphous SiO(2) nanoparticles, with large mesochannels and high specific surface areas, have been extensively and detailedly evaluated using various cationic dyes (methylene blue, safranin O, crystal violet, brilliant green, basic fuchsin and rhodamine-6G), anionic dyes (acid fuchsin, orange II, reactive brilliant red X3B and acid red 1) and microcystin-LR. We use mesoporous 80TiO(2)-20SiO(2)-900 for the degradation of cationic dyes and MC-LR, due to the dominant adsorption of SiOH groups and synergistic role of coupled adsorption and photocatalytic oxidation. For anionic dyes, due to the adsorption results predominantly from TiOH groups, our strategy realizes the enhanced photocatalytic oxidation by strong surface acids and larger available specific surface area.

MSU-S mesoporous materials: an efficient catalyst for isomerization of alpha-pinene.

MSU-S((BEA)) and MSU-S((Y)) mesoporous molecular sieves with different Si/Al ratios were prepared and characterized by XRD, XRF, N(2) adsorption, (27)Al MAS NMR, NH(3)-TPD and 2,6-di-tert-butyl-pyridine adsorption. Their catalytic behavior for the liquid phase isomerization of alpha-pinene has been investigated and compared with conventional zeolites and mesoporous molecular sieves. The activity correlates well with the amount of the accessible acid sites on the catalyst surface.

Mesoporous bismuth titanate with visible-light photocatalytic activity.

Visible-light-driven mesoporous bismuth titanate photocatalyst, which possesses wormlike channels, mixed phase mesostructured frameworks, large pore diameter (approximately 6.1 nm), and low band gap energy (2.5 eV), has been successfully prepared via a modified evaporation-induced self-assembly technique (EISA).

Controllable and repeatable synthesis of thermally stable anatase nanocrystal-silica composites with highly ordered hexagonal mesostructures.

In this article, we report a controllable and reproducible approach to prepare highly ordered 2-D hexagonal mesoporous crystalline TiO2-SiO2 nanocomposites with variable Ti/Si ratios (0 to infinity). XRD, TEM, and N2 sorption techniques have been used to systematically investigate the pore wall structure, and thermal stability functioned with the synthetic conditions. The resultant materials are ultra highly stable (over 900 degrees C), have large uniform pore diameters (approximately 6.

Delamination and intercalation of layered aluminophosphate with [Al3P4O16]3- stoichiometry in water/alcohol/amine solutions.

Delamination and intercalation of a layered microporous aluminophosphate [Al3P4O16](3-) .3[CH3CH2NH3]+ (AlP) were carried out in water/ethanol/amine and water/methanol/amine solutions. A good colloidal dispersion and saturated amine intercalates of the aluminophosphate can be obtained in solutions with dielectric constants in the range 50-70 and an amine concentration of 10 mmol/g AlP.

Delamination and aromatic amine intercalation of layered aluminophosphate with [Al3P4O16]3- stoichiometry.

The delamination and intercalation of a layered microporous aluminophosphate, [Al3P4O16](3-).3[CH3(CH2)NH3]+ (AlP), with aromatic amine have been carried out and were followed by XRD and SEM measurements. The basicity of the amine plays an important role in this process, as do the dielectric constant of the solution and the amount of amine added.

General synthesis of mesoporous spheres of metal oxides and phosphates.

Monodisperse and high-surface-area mesoporous inorganic spheres of various compositions including metal oxides, mixed oxides, and metal phosphates are prepared by templating mesoporous carbon spheres which are replicated from spherical mesoporous silica. Due to the rigid and thermally stable framework of carbon template, the crystalline phases of the obtained metal oxide spheres can be readily tailored by controlling crystalline temperatures. Moreover, the sphere morphologies can be changed from solid structure to hollow structure in some cases by changing the polarity of the precursor, due to the hydrophobic nature of carbon template.
